I was finally able to convince my wife that I need a new 1911. My old one just wasn't making me happy. After a bit of discussion(ie begging, pleading, wining) she relented and I am the new owner of a Springfield Champion.:D

Now since I havn't had to test fire any new ammo for so long I couldn't remember how much I put through my former carry gun before I deemed it acceptable to carry. Since I know everyone here has plenty of opinions to spare.:neener:

How many rounds do you shoot before you consider your ammunition reliable for your gun?

Make sure your gun is reliable first.

Shoot 200-500 rounds of FMJ just to make sure everything feed and feels right.

Then go to defensive ammo testing.

I personally shoot about 100-200 rounds of JHP before I feel comfortable with it. Some recommend one box of 50 as good-enough.

What you really need to do after breaking-in gun & ammo combo is to regularly train with it. Shoot another box of defensive JHP regularly in addition to just FMJ. I shoot JHP monthly, but some do more and some less.

For a model 1911, I'd want to put at least 400–500 rounds through it before deeming it trustworthy. For a revolver, the number would be significantly lower, since there's less to go wrong.

[FJC]

CWL pretty much nailed my preferences for checking reliability of any gun I carry. I put a few hundred rounds of cheaper practice ammo through it just to verify it works in general and do any "break in."

I then put 100-150 rounds of the carry ammo I plan to use through the pistol.

Only then do I feel safe carrying that pistol.

I read the title to this thread and couldn't help but think:

"How in the world do you break in ammo?"

Personal Defense Ammunition Functional Reliability Test for Semiautomatic Handguns

This procedure provides an example test plan to perform functional reliability testing of personal defense ammunition with self-loading firearms. The intent of this procedure is to present a carefully planned test process that thoroughly assesses handgun/ammunition functional compatibility, and offers reasonably defined performance based accept/reject criteria.........
